Holds Together When Broken
The interlayer keeps the broken pieces bonded in place, so the panel stays in its frame and keeps working as a barrier even after impact. This is the whole reason laminated glass counts as a safety glass.
Safety Glass
Laminated and structural safety glass solutions using PVB, SGP, EVA, tempered laminated builds, security structures, railing glass, floors, canopies, and curtain wall applications.
Your Premier Laminated Glass Supplier
Laminated glass is made by bonding two or more glass plies together with a polymer interlayer under heat and pressure. The interlayer is what makes it a safety glass: if the panel breaks, the pieces stay stuck to it instead of falling out, so the glass holds together and keeps acting as a barrier. We supply builders, façade contractors, and OEMs worldwide, and we make each panel to suit the job — flat or curved, clear or decorative, simple safety glazing or heavy structural builds. Tell us what your project needs and we'll match the glass to it.

Laminated Glass Features
Blocks UV And Cuts Noise
PVB blocks almost all UV light, which protects what's behind the glass from fading. In acoustic grades, the interlayer also damps sound, giving you a quieter room without a thicker wall.
Strong Enough To Carry Load
With an SGP interlayer and tempered plies, laminated glass is stiff and strong enough to act as a structural element — floors you can walk on, railings that guard a drop, and canopies that span overhead.
Stays Clear And Bonded
A proper autoclave bond stays optically clear and free of bubbles or delamination for the life of the panel, so the glass looks as good in ten years as it did on day one.
Custom Options For Laminated Glass
- Choosing The Interlayer
Pick PVB for general safety and acoustics, SGP for structural strength, or EVA when you want to seal in a decorative insert or need extra moisture resistance. - Glass Type And Treatment
Choose annealed, heat-strengthened, or fully tempered plies, in clear, low-iron, tinted, reflective, or Low-E glass, depending on the strength and look you're after. - Thickness And Ply Count
Go from a simple 6.38mm two-ply safety glass to a thick multi-ply security or structural build. More glass and more interlayer mean more strength. - Shape, Edges And Holes
Order flat or curved panels with ground, polished, or beveled edges, plus any holes or cut-outs you need for fixings — all done before toughening. - Color, Inserts And Printing
Add colored interlayers, sealed-in fabric or mesh, or ceramic frit printing for borders, logos, or shading patterns.
Manufacturing Process Of Laminated Glass
Laminated glass manufacturing requires accurate glass preparation, clean assembly, controlled bonding, and strict final inspection. Each step affects the finished panel’s optical clarity, structural strength, edge quality, and long-term durability. Before lamination, the glass must be cut, shaped, drilled, edged, washed, and heat-treated according to the final application, because many machining processes cannot be carried out after tempering or lamination.
Cutting And Edging: The glass is first cut to the required size according to the drawing or installation layout. After cutting, the edges are ground, polished, beveled, or seamed to remove sharp corners and improve handling safety. Good edge quality also helps reduce the risk of breakage during tempering, lamination, installation, and long-term use.
Drilling And Cut-Outs: Holes, slots, notches, countersinks, and special cut-outs are processed before tempering and lamination. These openings are usually made for fittings, hinges, bolts, railing systems, or façade hardware. Once the glass is tempered or laminated, it can no longer be drilled or cut, so every position and tolerance must be confirmed before production.
Tempering Or Heat-Strengthening: The prepared glass sheets are heat-treated to increase strength and improve safety performance. Tempered glass provides higher impact resistance and safe breakage, while heat-strengthened glass offers better flatness and lower optical distortion. The choice depends on panel size, installation method, safety requirements, and the final application environment.
Bending: For curved laminated glass, the glass is bent to the required radius before lamination. This process helps the finished panel keep its designed shape after bonding. Bending is commonly used for curved façades, canopies, railings, skylights, and decorative architectural glass where both appearance and safety are important.
Lamination: The glass sheets are assembled with PVB, SGP, EVA, or other interlayers, then bonded under controlled heat, pressure, or vacuum conditions. PVB is often used for standard safety glass, SGP provides higher stiffness and structural performance, and EVA is suitable for decorative inserts or special applications. Proper lamination creates a clear, strong, and durable glass panel.
Inspection And Packing: After lamination, every panel is checked for size, thickness, edge quality, clarity, bubbles, scratches, delamination, and hole position. Qualified glass is cleaned, labeled, separated with protective materials, and packed in strong wooden crates. Careful inspection and packing help ensure the glass arrives safely and is ready for installation.
Laminated Glass Applications
When glass carries weight or guards a drop, it has to stay in place even after it breaks. That's why balustrades, stair railings, and walk-on floors use laminated glass, usually with an SGP interlayer and tempered plies, so the panel stays intact and load-bearing.
On building envelopes, laminated glass blocks UV, controls noise, and stays in the frame if it's struck, so there's no falling glass below. It pairs with insulated and Low-E builds for façades, curtain walls, canopies, and overhead skylights.
Where security matters, adding plies and thicker interlayers lets the glass resist forced entry, bullets, or blast while still letting light through. Banks, embassies, control rooms, and storefronts rely on it.
Inside buildings, EVA lamination seals in colored films, fabric, or mesh, so partitions, doors, and feature walls can carry a design while still meeting safety rules.
